How many valence electrons are in neon
How many valence electrons are in neon?
Neon has eight valence electrons.
Explanation:
To find out the number of valence electrons in a neon atom,we need to look at the periodic table.
Neon is an element of group 18.Now just consider the unit place digit from group number.You are getting 8 which is equal to the number of valence electrons in neon.
Here is the another way to find out the valence electrons of neon.
The symbol of neon is Ne and the atomic number of neon is 10.So, it has nine electrons totally.
Now do the electronic configuration of neon.
Ne(10) =1s2 2s2 2p6
The valence shell is the outermost shell and the electrons that are present in valence shell is called valence electrons.
The valence shell or energy level can be identified by the highest value of principal quantum number ,n.Here the highest value of n is 2.So,the valence shell is the 2nd shell.
In 2nd shell we get 8 valence electrons.So each neon has eight valence electrons.
